Residual current circuit breaker EFI-P4 AC 63/0.3 002061633

Safety and protection in your electrical installation

The EFI-P4 AC 63/0.3 residual current circuit breaker (RCCB) is a key element ensuring the safety of using the electrical installation. Its task is to protect against electric shock, both in the case of direct and indirect contact with live conductors. Additionally, it protects electrical devices from damage caused by short circuits or leakage currents.

This four-pole (4P) circuit breaker with a rated current of 63A and a sensitivity of 0.3A is designed to operate in AC (alternating current) networks with a voltage of 415V and a frequency of 50/60 Hz. Its construction based on AC technology means that it reacts to alternating residual currents, which is standard in most home and industrial installations. The short-circuit strength of 10kA guarantees reliable operation even in the event of strong overvoltages.

Installation and application

The EFI-P4 AC 63/0.3 circuit breaker is mounted on a DIN rail, which facilitates its installation and replacement. A width of 4 modules allows for efficient use of space in the distribution board. The cross-section of the connected multi-core and solid-core wire up to 25 mm² ensures compatibility with most wiring used in residential and commercial buildings. Thanks to the IP20 degree of protection, the circuit breaker is protected against finger contact, which increases safety during operation.

The application of this circuit breaker is wide – it is ideal for lighting circuits, socket circuits and powering electrical devices requiring a high level of safety. It meets the IEC/EN 61008 standard, which confirms its compliance with European quality and safety standards.
